Placeholder. Story frame: L'Oréal My Skin Track UV / UV Sense turned battery-free UV sensing into a mass-distributed behavior tool. QSun, Barriere's Burn Notice stickers, sun-a-wear and SunSense show the format has room for multiple shapes — wristband, sticker, clip, app-only. The winner won't be the best sensor; it will be the one paired with the tightest reapplication-nudge loop.
